1 Claim.

This invention relates to wrenches and'more particularly to wrenches especially useful pipes or rods.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described, and, therefore, such changes and modifications may be made therefrom as do not affect the spirit of 5 the invention nor exceed the scope thereof as expressed in the appended claim.

In the drawing:

Fig. 1 is a plan view of my improved wrench, the jaws being in opened position.

Fig. 2 is a rear view of the same wrench.

Fig. 3 is a fragmentary plan view, with one plate removed, of the wrench shown gripping a rod; and

Fig. 4 is a perspective view of the pivotally connected cooperating jaws employed in the wrench. e

Referring to the drawing for a more, detailed description thereof, the numeral 5 indicates the handle, to the sides of which are secured spaced parallel plates 6 by means of rivets '7, said plates extending beyond the distal end of the handle and joined by means of a cross-piece 8, the function of which will be explained hereinafter. The numerals 9 and 10 indicate respectively the cor operating jaws of the wrench, said jaws having curved outer faces and pivotally connected to" each other at 11. Said jaws are adapted to swing between the mentioned plates 6, the jaw 9 being pivotally connected at 12 to said plates.

The outer face of the jaw 9 is provided with a projection 12, which engages the cross-piece 8 to limit the outward movement of the jaws. The jaw 10 has a curved outer face, which face rides on roller bearings 13 partially set in the. distal end of the handle, these bearings facilitating the movement of the jaw 10 as it moves to gripping position. Due to the taper of the jaw 10, the latter moves towards the jaw 9 as both jaws swing inwardly relative to the platesor, in other words, to gripping position, whereby the jaws 7 have a very effective grip on a pipe or rod or other article on which the wrench is used. The mentioned plates 6 are provided with toothed a'rcuate projections 15 extending from the exterior faces thereof, the teeth of said projections being adapted to engage a pipe or other article.

What is claimed is:

A pipe wrench comprising a handle, parall spaced plates extending from the handle, a pair of cooperating pivotally connected jawsmovable go between said plates, one-of said jaws being pivotally connected to the distal e'ndsof said" plates, and roller bearings carried by said handle for the other jaw, the latter being so curved that it is moved toward the cooperating jaw as both move between the plates to a gripping and supported position, said plates including teeth for engaging a pipe.

CARROL FISHER.
